Hey All,<br> I've searched through all the topics here, and well I'm probably more confused than ever. I was looking into getting 2 aftermarket Visonik Subs with Amp, and doing a custom fiberglass install for the show look etc. I've got the premium sound system in my car, therefore factor sub etc. I've read about using the cleansweep and everything else, because I want to retain my factory controls and the steering wheel controls if necessary. I've read about using a cleansweep and not, I guess I'll use the best solution. What happens if I don't use a cleansweep? We can't really figure out how to make it all work, and sound great. Any solutions are welcome to hear, and we aren't looking to integrate an iPod at all, so we don't need to worry about that. <p>Thanks.
